Drive train for a work machine, and work machine

Abstract

A drivetrain of a working machine, including at least a first driven axle and a second driven axle, wherein respective wheels of the first driven axle have a smaller effective diameter than respective wheels of the second axle, an electric traction motor, a transmission, and an axle disengagement device. A drive shaft of the transmission is connected to a driven shaft of the electric traction motor. A first driven shaft of the transmission is connected to a drive shaft of the axle disengagement device. A driven shaft of the axle disengagement device is configured to be connected to the first axle. A second driven shaft of the transmission is configured to be connected to the second axle. The driven shaft of the electric traction motor, the first driven shaft of the transmission and the second driven shaft of the transmission extend in one plane.

         2 . The drivetrain according to  claim 1 , wherein the drive shaft of the transmission also extends in the plane. 
     
     
         3 . The drivetrain according to  claim 1 , wherein the drive shaft of the axle disengagement device also extends in the plane. 
     
     
         4 . The drivetrain according to  claim 1 , wherein the driven shaft of the axle disengagement device also extends in the plane. 
     
     
         5 . The drivetrain according to  claim 1 , wherein respective shafts of the drivetrain extending in the plane are arranged axially parallel to one another. 
     
     
         6 . The drivetrain according to  claim 1 , wherein the first driven shaft of the transmission is arranged coaxially to the driven shaft of the electric traction motor and wherein the second driven shaft of the transmission is arranged offset to the first driven shaft of the transmission. 
     
     
         7 . The drivetrain according to  claim 1 , wherein the plane extends in a transverse direction of the vehicle. 
     
     
         8 . The drivetrain according to  claim 1 , wherein the transmission is configured to provide a neutral position. 
     
     
         9 . The drivetrain according to  claim 1 , wherein the drivetrain comprises a control device for the axle disengagement device, and wherein the control device is arranged on the transmission. 
     
     
         10 . The drivetrain according to  claim 1 , further comprising a parking brake, which is integrated into the transmission. 
     
     
         11 . The drivetrain according to  claim 1 , wherein the first driven shaft of the transmission is connected to the drive shaft of the axle disengagement device by a first cardan shaft and wherein the second driven shaft of the transmission is connected to the second axle by a second cardan shaft. 
     
     
         12 . A working machine with the drivetrain according to  claim 1 , wherein the working machine has at least a first driven axle and a second driven axle and wherein respective wheels of the first axle have a smaller effective diameter than respective wheels of the second axle. 
     
     
         13 . The working machine according to  claim 12 , wherein the first axle is arranged offset to the second axle in a vertical direction of the vehicle. 
     
     
         14 . The working machine according to  claim 12 , wherein at least the first driven axle or the second driven axle comprises a wheel hub transmission.
